1. Install the molded case circuit breaker (MCCB) or earth leakage circuit breaker (ELCB) (with overcurrent protection function) recommended for each inverter on the inverter input side (primary side) to protect wiring. Do not use a circuit breaker that exceeds the recommended rated current.
2. An MCCB or ELCB is also used if isolating the inverter from the power supply, and therefore the magnetic contactor (MC) recommended for each inverter should be installed if required. Please note that if installing a coil such as an MC or solenoid near the inverter, connect a surge absorber in parallel.
3. If you wish to retain the integrated alarm signal issued if the protective function is triggered even when the inverter main power supply is cut off, or to constantly display the keypad, connect these terminals to the power supply. (on FRN0008G2[][]-2G or higher /FRN0008G2[][]-4G or higher) The inverter can be run even without inputting the power supply to these terminals.
5. Remove the shorting bar between the inverter main circuit terminals P1 and P(+) before connecting the DC reactor (DCR) (option). Be sure to connect the DC reactor in the case of FRN0139G2[][]-4G ND / FRN0288G2[][]-2G HND / FRN0179G2[][]-4G HND, HD, ND specification and FRN0346G2[][]-2G or higher / FRN0217G2[][]-4G or higher inverters. Use a DC reactor (DCR) when the capacity of the power supply transformer is 500 kVA or more and is 10 times or more the inverter rated capacity, or when there are "thyristor driven" loads.
6. FRN0288G2[][]-2G or lower / FRN0217G2[][]-4G or lower inverters are equipped with a built-in braking transistor, allowing direct connection of braking resistors between P(+) and DB. If connecting a braking resistor (DB) (option) to FRN0346G2[][]-2G or higher / FRN0261G2[][]-4G or higher inverters, a braking unit (BU) (option) is necessary. A built-in braking resistor is connected between terminals P(+) and DB on FRN0046G2[][]-2G or lower /FRN0023G2[][]-4G or lower inverters. If connecting a braking resistor (DB), be sure to disconnect the built-in braking resistor.
7. This terminal is used for grounding the motor. Connect if required.
8. Use twisted wire or shielded wire for control signal lines. Shielded wires are generally grounded, however, if subject to significant induction noise from outside, it may be possible to suppress the effect of the noise by connecting wires to [CM]. Isolate control signal lines from the main circuit wiring as best as possible, and do not run inside the same duct (a distance of 10 cm or greater is recommended.) If lines intersect, ensure that they do so almost perpendicularly to the main circuit wiring.
9. Each of the functions described for terminals [FWD] and [REV], terminals [X1] to [X9] (digital input), terminals [Y1] to [Y4] (transistor output), terminal [Y5A/C], and terminal [30A/B/C] (contact output) indicate functions assigned by factory default.
11. These are the switches on the control PCBs and are used to specify settings for inverter operation. Refer to the User's Manual Section 2.2.7 for details.
12. Safety function terminals [EN1] and [EN2] are disabled with SW7 (2-pole switch) on the control PCB by factory default. If using this terminal function, be sure to change the respective SW7 switches to the OFF position and connect.
13. Install a thermal relay if necessary. Make the circuit breakers (MCCB) or the magnetic contactors (MC) trip by the thermal relay auxiliary contacts (manual recovery).
14. [0V] and (0V) are separated and insulated.
15. The factory default setting for SW1 of FRN[][][][]G2E-4G is "SOURCE".
